2...Nxb6
this sacrifice gives Black a fighting chance otherwise he will be overwhelmed or mated [2...Nd6 3.Kd3 Be4+ 4.Kc3 Ka5 (4...Bf5 5.Ne5 Ka5 (5...Be6 6.Kb4 Nf5 7.Bc5 ) 6.Nc4+ Nxc4 7.Kxc4 Be4 8.Kc5 ) 5.Ne5 Nb5+ 6.Nxb5 Kxb5 7.Kd2 Bd5 8.Ke3 aiming for Kc7 winning; 2...Bg2 3.Kd3 Bf1+ (3...Bd5 4.Kc3 Ka5 (4...Nd6 5.Kb4 Ne4 6.Nb8# ) 5.Bc5 Bg8 (5...Be6 6.Bb4+ Ka6 (6...Ka4 7.Nc5# ) 7.Nc5+ Kxb6 8.Nxe6 ; 5...Ka4 6.Bb4 Nxb6 7.Nxb6# ; 5...Ka6 6.Kb4 Nxb6 7.Nb5 Nxd7 (7...Bc6 8.Nb8# ) 8.Nc7# ) 6.Nc6+ Ka4 7.Nd8 Kb5 8.Bf2 Nd6 9.Kd4 Nc8 10.Ke5 Ka6 11.Nf6 Bb3 12.Ne8 Nxb6 13.Nc7+ Ka7 14.Nde6 Bxe6 15.Kxe6 wins the knight) 4.Kc3 Na3 (4...Nd6 5.Kb4 Ne4 6.Nb8# ; 4...Na5 5.Nb8# ) 5.Kb3 Nb5 (5...Nc4 6.Nc5+ Kxb6 7.Nd3+ Kc7 8.Kxc4 ) 6.Bc5 Bh3 7.Nb8+ Ka5 8.Nbc6+ Ka6 9.Nb4+ Ka5 10.Nac6+ bxc6 11.b7 queening; 2...Bd5 3.Kd3 Nd6 4.Kc3 Ka5 5.Be5 Nb5+ 6.Nxb5 Kxb5 7.Bc7 Be6 8.Nf6 Kc5 (8...Kc6 9.Kd4 ) 9.Kd3 Bf5+ 10.Ke3 Bg6 11.Kf4 Kb5 12.Ke5 and White infiltrates]

4...Bg4
has Black found a drawing resource despite his two piece deficit?

5.Kc4
